HOT-WATER AND STEAM BOILER.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed. January 9, 1912. Serial No. 670,236.

To all whom it may concern:

Be it known that I, PHILIP BRUNK, a citizen of the United States,residing at Lorain, in the county of Lorain and State of Ohio, haveinvented certain new and useful Improvements in Hot-Water and SteamBoilers, of which the following is a specification.

This invention relates to improvements in hot water or steam boilers forheating purposes and has for its object to provide a boiler of simple,practical and inexpensive construction, which is economical in the useof fuel, is easily cleaned and may be readily disconnected for thepurpose of making repairs.

With the above and other objects in View as will be understood, theinvention consists in certain combinations and arrangements of the partshereinafter fully described and the novel features thereof will be particularly pointed out in the appended claims.

For a clear understanding of the invention, reference will be had to theaccompanying drawings which illustrate a preferred embodiment thereof,and in the drawings like characters of reference indicate corre spondingparts.

Figure 1 is a front elevation of a hot water boiler illustrating myinvention, the

casing being in section to more clearly show the construction; Fig. 2 isan end view of Fig. 1, the casing being shown in section; Fig. 3 is aperspective view on an enlarged scale of one of the manifolds; Fig. 4:is a detail sectional view showing the manner of connecting the coilpipes to the manifolds, and Fig. 5 is a fragmental portion of amodification of Fig. 1.

In the drawings 1 represents a plurality of spaced vertical pipe coilshaving their horizontal portions 2 and 3 oppositely inclined. The lowerfree end of each coil is connected to an inlet or return manifold 4: andthe upper free ends of said coils to a similar outlet manifold 5. Aplurality of similar pipe coils 6 are arranged in the spaces between thecoils 1 and in a suitable spaced relation thereto to permit freecirculation of heated air between the pipes. The free ends of the pi ecoils 6 are connected to an inlet manifold 'l' and an outlet manifold 8similar to those already mentioned. Each manifold consists of anelongated hollow casting 9 having a fiat side 10 and a round ingopposite side 11 which is provided with a central hollow boss 12. Saidbosses are connected by means of pipes to radiators of ordinaryconstruction. The flatside 10 of the casting is provided with aplurality of holes 13, and to said side is remov ably secured, by meansof tap bolts 14: or in any suitable manner, a plate 15 having openings16 corresponding to the holes 13 in the cast- 1ng and adapted toregister therewith. The openings are countersunk as indicated at 17 andthe free ends of the pipe coils are fastened therein as best shown inFig r. The p1pe coils, arranged and connected to the manifolds asdescribed, are, inclosed in a suitable casing 18 with the bosses 12 ofthe casting 9 projecting through the sides thereof, and recessed bars11') carried by the front and rear sides of the casing support said pipecoils and keep them the proper lateral distance apart. The pipe coilsmay be heated in any suitable manner, but preferably by means of a gasburner consisting of a plurality of transversely extending perforatedtubes 20 supported in the casing and connected to a longitudinal pipe 21provided with a shut off valve 22 for controlling the gas supply.

The hollow bosses 12 of each outlet manifold 5 or 8 and each inletmanifold 4: or 7 may be connected to any ordinary radiator or a seriesof radiators in the usual manner. Or the outlet manifoldds 5 and 8 maybe connected by a pipe 23, from which extends a branch 24 leading to aradiator or a series of radiators, and the inlet manifolds 4c and 7 maybe similarly connected by a pipe 25 and branch 26 to the radiators.

The casing 18 is provided with a chimney opening 27 and also with aplurality of suitable doors such as indicated at 28 and 29 for obtainingready access to the interior of the boiler to clean the same or makerepairs.

In the modification illustrated in Fig. 5, a hollow casting 30 servesthe purpose of a steam dome, and at each side thereof depends a hollowportion or manifold 31, having a flat inner side 32 provided withopenings 33 similar to the casting 9. Pipe coils 34 and 35 are connectedto plates 36 which are removably secured to the fiat sides 32 in themanner already described. Steam outlet pipes 37 lead from the casting 30and may be connected to a radiator or a series of radiators in anysuitable manner.

From the foregoing it is apparent when the hot 'water boiler isconnected to the radiators, that a gas flame or other heating meansunder the pipe coils will quickly heat the same and cause the hot waterto circulate; or in the care of the steam boiler, if the hollow casting30 is partially filled with water, steam would be generated and driventhrough the radiators.

The boilers may be quickly cleaned as the pipe coils are readilyaccessible, and should the pipe coils become choked, the plates 15 and86 may be easily disconnected from the manifolds and the pipes be blownout.

It is to be understood, that slight changes in the details ofconstruction and arrangement of the parts may be resorted to, withoutsacrificing any of the advantages or departing from the principle of theinvention.

Having described my invention what I claim is:

1. In a heating boiler, the combination of a plurality of pipe coils, apair of hollow castings having a plurality of openings, a pair of plateshaving the free ends of the pipe coils fixed therein and adapted toregister with the openings in said castings, means for removablysecuring the plates to the hollow castings, a casing inclosing the pipecoils, means for heating the pipe cells, and means for connecting thehollow castings to a radiator, substantially as described.

2. In a heating boiler, the combination of a plurality of pipe coils, apair of hollow castings having a flat side provided with a plurality ofopenings, a pair of plates having countersunk holes arranged to registerwith the openings in the flat sides of said hollow castings and the freeends of the pipe coils rolled in said holes, means for removablysecuring the plates to the flat sides of said hollow castings, a casinginclosing the pipe coils, means for supporting the pipe coils from thesides of the casing, means for heating the pipe coils, and means forconnecting the hollow'castings to a radiator,

in longitudinal spaced relation and having their free ends extendinglaterally in the same direction, similar pipe coils arranged in thespaces between the first pipe coils and having their free ends extendingin the opposite direction to the free ends of the first named pipecoils, a plurality of hollow elongated castings, a plurality of plateshaving the free ends of the pipe coils fixed therein, means forremovably securing the plates to the hollow elongated castings, a casinginclosing the pipe coils, means for supporting the pipe coils from thesides of the casings, heating means arranged below the pipe coils, andmeans for connecting the hollow elongated castings to a radiator,substantially as described.

4. In a heating boiler, the combination of a plurality of vertical pipecoils arranged back of each other in spaced relation, other pipe coilsarranged in the spaces between the first mentioned pipe coils and havingtheir free ends extending in the opposite direction to the free ends ofthe first named pipe coils, a hollow elongated casting fixed to thelower free ends of the first and second mentioned pipe coils, a hollowdome casting having sets of openings, plates having the upper free endsof the first and second mentioned pipe coils fixed therein and adaptedto register with said sets of openings, means for removably securing theplates to the hollow dome casting, a casing inclosing the pipe coils,means for supporting the pipe coils from the sides of the casing,heating means arranged below said pipe coils, means for connecting thehollow elongated castings to a radiator, and means for connecting thehollow dome casting to said radiator, substantially as described.

In testimony whereof I afiix in presence of two witnesses.
